Researchers have done a good job at creating robotic versions of animals like dogs, cheetahs, and even load-hauling mules. But this ongoing research proves just how challenging it is to recreate the smallest creatures on Earth. It will be quite a few years before Harvard’s Robobee is able to fly around a controlled laboratory setting all by itself, and even longer before it tackles the uncertainty of the outside world where even the tiniest of breezes can throw it off course. But with this recent accomplishment, it’s hard to imagine a future where smacking a mosquito buzzing around your ear doesn’t come with the risk of destroying an incredibly expensive micro drone trying to spy on you.
